IMath.Sum

Fore Syntax

Sum(Values: Array): Double;

Fore.NET Syntax

Sum(Values: System.Array): double;

Parameters

Values. Array of real numbers.

Description

The Sum method returns the sum of elements of the specified array.

Comments

If an array of real numbers contains gaps, the function returns error.

The function works correctly with both one-dimension and two-dimension arrays.

Fore Example

To execute the example, add a link to the MathFin system assembly.

Sub UserProc;
Var
    r: Double;
    Arr: Array[4] Of Double;
Begin
    Arr[0] := -5;
    Arr[1] := 15.08;
    Arr[2] := 30.12;
    Arr[3] := 5.94;
    r := Math.Sum(Arr);
    Debug.WriteLine(r);
End Sub UserProc;

After executing the example the console window displays the sum of array elements equal to 46.14.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.MathFin;
…
Public Shared Sub Main(Params: StartParams);
Var
    r: double;
    Math: MathClass = New MathClass();
    Arr: Array[4] Of double;
Begin
    Arr[0] := -5;
    Arr[1] := 15.08;
    Arr[2] := 30.12;
    Arr[3] := 5.94;
    r := Math.Sum(Arr);
    System.Diagnostics.Debug.WriteLine(r);
End Sub;
